Simbi isina ngura zvinhu
Nepo sarudzo inodhura kupfuura yendarira, simbi yakasimba, yakasimba simbi. Kunyange ndarira iri chiumbwa chemhangura, simbi isina chinhu isimbi yesimbi yakasanganiswa nekromium uye nickel.
Hunhu hwezvinhu zvinoreva kuti mavhavha aya anokwanisa kurwisa zvinobatika. Simbi zvakare inokwanisa kushanda mune tembiricha yakawanda kupfuura yendarira uye inogara kwenguva refu. Stainless simbi mavharuvhu ndiyo yakanyanya kunaka sarudzo yekumanikidza uye tembiricha mamiriro. Izvowo zvakare chinhu chakakura chekurwisa ngura.
Stainless simbi 316, inonyanya kuora kusagadzikana nekuti ine yakawanda nickel uye zvakare ine molybdenum. Iko kusanganiswa kwesimbi, nickel uye molybdenum kunoita mavhavha kunyanya anodzivirira kuma chloride uye anonyanya kubatsira munzvimbo dzegungwa.
Brass zvinhu
Brass imhangura chiwanikwa zvinoreva kuti yakasimba pane plastiki. Iri simba rekuwedzera rinovaita, kunyangwe isiri iyo inodhura sarudzo yevhavha, inodhura kupfuura PVC kana mavhavha epurasitiki.
Brass musanganiswa wendarira uye zinc, uye neapo dzimwe simbi. Nekuda kwehunhu hwayo sesimbi yakapfava, inokwanisa kurwisa ngura zvakanyanya kupesana nemavharuvhu epurasitiki.
Brass zvigadzirwa zvine zvidiki zvemutobvu. Kazhinji yenguva zvigadzirwa zvemhangura zvinoumbwa neisingasviki 2% lead, zvisinei izvi zvinokonzeresa kusahadzika kune vazhinji. Muchokwadi, iyo FDA haibvumire mavhavha endarira ari kushandiswa kunze kwekunge ari anozivikanwa asina-lead. Shandisa kungwara pakusarudza vharuvhu zvinhu zvako zvinotevera chirongwa.
Musiyano pakati pesimbi isina kuchena nendarira
Uku kuenzanisa kweasina simbi mavharuvhu nemhangura emhangura zvakatipa isu misiyano yakakura yekufunga.
Mariro: Mavhavha esimbi esimbi anodhura kupfuura mavharuvhu endarira. Kana zvese zvinhu zvikasangana nezvinodiwa zveprojekiti yako uye bhajeti iri kunetsekana, funga kushandisa mavharuvhu endarira kuchengetedza pamari.
FDA Kubvumidzwa: Iyo FDA haibvumire mavhavha endarira kunze kwekunge iwo ari anozivikanwa akatungamira-emahara, ichivaita sarudzo yakashata yekushandisa muindasitiri yezvikafu. Stainless simbi, zvisinei, inogamuchirwa neDFA kuti ishandiswe muindasitiri.
Corrosion Resistance: Brass inokwanisa kumira ngura zvirinani kupfuura plastiki. Nekudaro, simbi isina tsvina ichiri chakanakisa mudhipatimendi rekurwisa ngura, kunyanya munzvimbo dzegungwa.
